While I'm not familiar with Sybase, so I don't know wether or not these scripts you speak of were bundled with the software (in which case there might be some unbelieveably slim chance that someone on the net had posted something about them) or whether they were custom writen for your company (in which case no, you won't be able to find any sort of documentation for them).

However, if you just wish to interpret them, there are several things you could do... The easiest would be simply to try to track down whomever wrote them originally and see if you can get them to explain it to you. Sometimes author's will put an email address in the headers of a script so they can be contacted if bugs are found.
short of that, you could learn perl, which, even if you had someone sit down and explain to you what the script did, is the only real way you're ever going to be able to actually understand the script. Perl isn't an easy language to learn if you have no expirence, but its a very valueable thing to know.
